The current research s first exploratory impulse was to look into the role of language in the aristotelian philosophical approach, with the assumption that language would be the means by which we express knowledge acquired from perception. As perception is always of the particular, language would play a crucial role in the construction of a generalizing apprehension of the real and, therefore, would make systematic knowledge possible. However, such a premise assumes that perception would be configured as a means of access to an external reality, or the real, in other words. Thus, in the course of the investigation, it became necessary to establish what the aristotelian understanding of perception is, if it is possible to know through perceptual processes and if, according to Aristotle, it is possible to say that there is the real to be apprehended through perception. In this sense, the current dissertation is dedicated to investigating the process of knowledge apprehension through the path: aísthēsis, mneme and empeiría, in order to answer those questions.
